centos、XShell安装mysql8教程！

1.首先查看自己的阿里云服务器的cenos版本

去官网MySQL找对应的版本，如果是centos7可以从网盘链接下载。

提取码：bkdz

el后面的数字就是版本，rpm包内有一个叫“el7.x86_64.rpm”，后面的7就是centos7的版本，下载rpm包。

安装前先执行

rpm -qa|grep mariadb

卸载CentOS自带的mariable 可能数字不一样，需要修改。

rpm -e mariable-libs-5.5.52-1.el7.x86_64 --nodeps

首先解压安装包

tar xvf mysql-5.7.18-linux-glibc2.5-x86_64.tar.gz

安装包的版本根据自己的进行更换。

输入ls查看解压后的包

ls

一定要按顺序安（在阿里云服务器内Ctrl+Insert是复制 Shift+Insert是粘贴）

mysql-community-common-8.0.26-1.el7.x86_64.rpm
mysql-community-client-plugins-8.0.26-1.el7.x86_64.rpm
mysql-community-embedded-compat-8.0.26-1.el7.x86_64.rpm
mysql-community-libs-8.0.26-1.el7.x86_64.rpm
mysql-community-libs-compat-8.0.26-1.el7.x86_64.rpm
rpm -ivh mysql-community-client-8.2.0-1.el7.x86_64.rpm
rpm -ivh mysql-community-icu-data-files-8.2.0-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-8.2.0-1.el7.x86_64.rpm
rpm -ivh mysql-community-server-debug-8.2.0-1.el7.x86_64.rpm

如果安装出错，先接着安下一个，最后把这些命令全部执行一次。

yum -y install numactl
yum install openssl-devel
yum -y install autoconf
yum install perl-JSON.noarch -y
yum install perl.x86_64 perl-devel.x86_64 -y

初始化数据库

mysqld --initialize --console

目录授权

chown -R mysql:mysql /var/lib/mysql/

启动mysql

systemctl start mysqld #启动
systemctl stop mysqld #停止
systemctl restart mysqld #重启

最后执行

systemctl status mysqld

出现这个就可以了

报错：版本不对，找到对应的centos版本。
